The WBX is a wide bandwidth transceiver that provides up to 100 mW of output power and a noise figure of 5 dB. The LO's for the receive and transmit chains oper ate independently, but can be synchronized for MIMO operation. The WBX provides 40 MHz o

幅度与相位相结合的多进制正交幅度调制（MQAM）技术利用载波幅度和相位传递信息比特，具有充分利用带宽、抗噪声能力强等优点，广泛应用于电视、微波通信、光传输等系统。MQAM发送器是研究MQAM调制解调技术的基础。ADL5385是一款硅半导体单片正交调制器件，其频率范围为50～2200MHz。探讨了利用ADL5385设计的155Mb/s（STM鄄1）128样点QAM发送器，为研究MQAM提供借鉴。
